SVNTEJJ'ON United States Patent O 3,222,060 XUGGING MACHINE ke Waldemar Svantesson, Bandhagen, Sweden, assigner to Lindaco Aktiebolag, Stockholm, Sweden, a company of Sweden Filed Dec. 2, 1963, Ser. No. 327,207 Claims priority, application Sweden, Jan. 8, 1963, 153/63 8 Claims. (Cl. 271-39) This invention relates in general to jogging machines or machines for aligning sheets of material such as paper and, in particular, to a new and useful device for aligning the edges of a stack of sheet material.

The present invention is an improvement over prior art machines for aligning the edges of sheets of material particularly in respect to the simplicity of construction and in the small number of parts employed for a jogging machine and in respect to the resilient mounting means for a vibratory table ensuring that the table is vibrated in a manner to give the most ecient jogging of the sheets to bring them into alignment.

In accordance with the invention, there is provided a jogging machine of a construction which comprises a vibratory table arranged in a slanting position to support a pile of sheet material or leaves. Two walls for aligning adjacent edges of the sheet material are arranged on the table substantially perpendicular to the surface thereof and to each other. The table is mounted in a novel manner on resilient supporting members and a vibration motor is connected to the table for causing its continuous vibration. In prior jogging machines of this type, the vibration means has caused the table to vibrate in all directions in its own plane. It has been found that a more rapid and satisfactory operation is obtained if the table is caused to vibrate in lone direction only. That is parallel with the bisector of the angle formed by the side walls of the table. According to the invention, such unidirectional vibrations are produced by supporting the table by spring means which comprises leaf springs mounted in a plane extending substantially perpendicularly to the table and to the bisector of the angle formed between the two walls.

Accordingly, it is an object of this invention to provide an improved jogging machine.

A further object of the invention is to provide a jogging machine which includes a mounting base with a table mounted thereon for adjustable positioning at an inclination, the table having upstanding edge Walls which are arranged substantially perpendicular to the table and to each other and with means connected to the table for vibrating the table, and wherein, the table is mounted on the mounting base by means of spring elements which are mounted in a plane which extends substantially perpendicularly to the table and to the bisector of the angle between the edge walls of the table.

A further object of the invention is to provide a jogging machine which is simple in design, rugged in construction and economical to manufacture.

The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of the invention, its operating advantages and specific objects attained by its use, reference should be had to the accompanying drawings and descriptive matter in which there is illustrated and described a preferred embodiment of the invention.

FIG. 2 is a rear side perspective View of the jogger indicated in FIG. 1.

3,222,060 Patented Dec. 7, 1965 Frice Referring to the drawings, in particular, the invention embodied therein comprises a jogging machine Vincluding a base portion generally designated 1 of substantially U-shaped configuration which includes a bottom wall 1a and upright side walls 1b and 1c which extend upwardly from each end of the bottom wall. The bottom wall 1a is provided with suitable openings 4 for securing this portion to a table -or oor mounting.

A base plate 2 is pivotally mounted on bolt members 15, 15 journalled on the upper ends of each of the legs 1b and 1c. The plate 2 may be pivoted to a desired operating inclination and secured in such position by tightening winged nut members 3, 3 threaded onto the outwardly projecting threaded ends of the bolts 15, 15. In order to facilitate the operation of the nuts 3, 3, one bolt 15 is provided with a right-hand thread and the other bolt is provided with a left-hand thread.

In accordance with the invention, a substantially square table 5 is mounted on the plate 2 parallel to oblique side edges 2a, 2a thereof. The mounting of the table 5 is such that one diagonal thereof extends parallel to the horizontal axis of the plate 2 and the other diagonal extends perpendicular to this axis. The top corner of the table 5 has a recess 6, and the bottom corner has a recess 7. These two recesses 6 and 7 facilitate lifting of a pile of leaves, or sheet material, from the table. The table 5 carries side -walls 8, 8 Varranged along side edges 5a, 5a of table 5 for supporting two adjacent edges of the leaves which are to be handled by the jogging machine. The leaves, particularly very thin leaves, have a tendency to creep up along the walls 8, and for this reason the angle between the walls and the table is made somewhat less than t-o reduce this tendency. A preferable inclination of the walls 8 with the surface of the table 5 is between 85 and 89, with the optimum being 87.

An electric motor having a shaft 10a carrying an eccentric weight 10b is secured by means of a flange 10c to the table 5 with bolts 9. The axle of the shaft 10a extends substantially perpendicularly to the table 5 and has its front end positioned within a housing 11 which is situated just below the table 5. An eccentric weight-10b is fastened to the front end of the shaft 10a within the housing 11 and when the shaft is rotated, the weight produces vibrations causing the vibration of the table in its own plane. The plate 2 is provided with an opening to permit the motor with the housing portion 11 to extend therethrough without making any contact therewith.

In accordance with a feature of the invention, the table 5 is mounted on the plate 2 by spring means comprising four leaf springs 12 which are substantially symmetrically positioned around the shaft 10a. One end of each of the leaf springs 12 is fastened to the base plate 2 by means of a block holder 14 which is secured to the bottom and the other end is secured to the table 5 by means of a holder 13 which is secured to the bottom of the table. The springs are held by the holders 13 and 14 in a plane extending substantially perpendicularly to the table 5 and perpendicularly to the central diagonal of the table which also bisects the angle between the walls 8, 8.

When the motor is operated to produce vibrations of the table 5, the leaf springs 12 ensure that the maximum vibrations act substantially parallel to the slanting diagonal of the table. Since the leaf springs 12 are all held so that they are substantially perpendicular to the central diagonal of the table 5 they permit little or no movement of the table 5 relative to the base plate in directions parallel to the horizontal diagonal of the table 5. The jogging of the pile of leaves will therefore take place in directions parallel to the central diagonal of the table 5 which in the position of the table 2 slants downwardly from the center of the recess 6 toward the recess 7 at the lowermost corner of the table 5.` The result is that the table operates in a most efiicient manner to cause alignment of the edges of the sheet material with the walls 8, 8.

While a specific embodiment of the invention has been shown and described in detail to illustrate the application of the inventive principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
